The reaction of PSCl 3 , RPSCI 2 , (EtO) 2 PSCI, [(CH 3 ) 2 N] 2 PSCl and PSBr 3 with CH 3 AICl 2 , EtAlCl 2 , EtAI(OEt) 2 , Et 3 A1, Ph 3 A1 and (i‐C 4 H 9 ) 3 Al has been studied. The preparation of thiophosphonic dihalides, RPSX 2 [R =CH 3 , C 2 H 5 , i‐C 4 H 9 ; X =C1, Br], thiophosphinic halides, RR′PSX [RR′ = C 2 H 5 , i‐C 4 H 9 , Ph; X = C1, Br, and R′ = CH 3 , R′ = C 2 H 5 , X =Cl], as well as tertiary phosphine sulfides, R 3 PS [R = C 2 H 5 , i ‐C 4 H 9 , Ph] is described. The preparation of [(CH 3 ) 2 N] 2 P(S)Et is also reported.
